z'l claims. (C11 1s z) The present invention relates to mechanisms forautomatically unloading 'cured tires from presses for shaping and curingtires, and particularly presses of the diaphragm shaping and vulcanizingtype such as shown in applicants prior Patents No. 2,495,664, January24, 1950, and No. 2,699,572, January 18, 1955.

We have omitted altogether the showingy of the top half of the mold ofthe mechanism for manipulatingv it as this has nothing to do with thepresent invention, any typeof press operating mechanism beingadaptable."

We have also Vomitted ,showing-the, wiring diagram vand certainvswitches by which themovements of 'the mech# anism areautomaticallyfcontrolled,"as, suchdetails may be designed by any4qualiied electricalengineer'when the sequence of operations is fullyunderstood, f

The apparatus for ,manipulating the diaphragm or other tireformingmech'anisinsjs also,oinitted,itY being suicient rto say, withrespectlto diaphragm presses, that after the cure is completed the upperhalf of the mold is raised, leaving the cured tire on the diaphragm inthe lower mold section. The diaphragm carrying the cured tire is thenraised above the lower mold section, whereupon stripping arms movebeneath the tire to a horizontal position and simultaneously thediaphragm is withdrawn from the cured tire. Thereis then a short pausein the movement of the stripping mechanism to allow the extendeddiaphragm to be returned to its seat in the lower mold section. `Thisleaves the cured tire at the upper extremity of the diaphragm, restingupon the stripping arms. It has been the practice heretofore for theoperator to remove the tire manually from the arms and it is the objectof this invention to provide automatic means for removing the tire fromthe press.

In accordance with the present invention, and referring particularly todiaphragm presses, when the diaphragm returns to its seat in the lowermold section, one of the stripping arms, which will be called theunloading arm, continues its upward movement which is preferablyextended over the top of the diaphragm, while the other arm, which willbe called the conveying arm, remains in its raised position. This willcause the tire to assume a tilted Vposition and when the angle issuiiicient the tire will slide by gravity over the top of the diaphragmand out of the press, where it may fall upon a gravity conveyor whichremoves it from the press. Either the front or the rear stripping armmay be selected as the arm to be moved to the greater extent, dependingupon whether the tire is to be discharged at the front or rear of thepress, and while the drawings and description are directed to a rearunloading press, the invention may likewise be applied to a frontunloading press by merely rel stood that the showing is of the bestknown and preferred form of the invention. The device is illustrated asapplied to'dual diaphragm presses with two moldunits but shown in Fig.1.

Fig. 1 is a vertical section through a lower mold showing the diaphragmin its extended position and returnedv to its seat in the lower moldsection. In this view, the

""tre is shown in iull lines at the level of the top of the extendeddiaphragm just before the actual unloading operation is started. Thedotted lines show the tire at other points in its travel.

In vthis view the arms are shown in fulllines in their lowered or idle position and in dotted lines at the endof their joint movement.

Fig. 3 isa view similar to Fig. 2 but showing both arm raised in fulllines and the unloading arm, in dotted lines, in the positions where thetire starts to move out of the press by gravity. On this view the'fullpath of the rollers onthe end of the loading arm is traced.

Fig. 8 isa view showing what-isl known as the cylinder bellcrank.' 4' 5In the drawings, the bed of the` press is indicated by the numeral 1,the heated lower platen by the numeral 2, and the lower moldsection bythe numeral 3. The'diae phragm is indicated by the numeral 5, beingshown with the lower diaphragm ring 6 seated in the lower mold section.The diaphragm, in full lines, is fully extended after it is strippedfrom the tire and lowered to its seat in the. lower mold section 'withthe ring 7 at fully raised position. The diaphragm is stripped from thetire simultaneously with the movement of the arms from a to b position,as

While the right or conveying arm remains in the b position, lthe tiltingor unloading arm moves to the position shown in Fig. 5, which causes thetire to slide down by gravity until it falls on the conveyor 10. This isa 'gravity conveyor so that the tire moves out of the machine and, ifdesired, on a main conveyor (not shown) which may' serve a row ofpresses.

The conveyingv arm Located on the bed plate 1, at one side of thediaphragm, is a boxlike, upwardly and rearwardly extending stanchion 11,in the upper end of which is a shaft 12 on which the conveying arm,indicated as a whole by the numeral 15, is journaled. Because the pressshown herein is a dual press, the arm 1S is formed with a centrallylocated, U-shaped section, to the arms of which are attached plates 16which are journaled on bearingson the reduced ends of the shaft 12. Attheir lower ends the vertical arms 15 are provided with elongated,lateral extensions 18 which extend to the sides of the vtwo diaphragmsf5, as shown in Fig. 7. To each extension are attached two parallel,rearwardly extending brackets 20,

in the outer end of' each of which is supported a freely rotatabletubing 21. Also attached to each extension are a series of outwardlyextending ,brackets 22, in' the outer ends of which are locatedstationary tubes 24. 'As shownin Fig. 3,-wh`en 'the conveying arm israised to its.upper limit andthe unloading arm is likewise raised to itsI`upperA limitfthe.n arms `form a support for the tire ber g, formingtheconnection between the two members oft-the -U-'shaped arm 15. Bracket 25is pivoted at 26 to the clevis of a link 27, the lower end of which isthreaded in a second clevis 30, in which it is held inadiusted-position.' The lower end of this link is connectedtofa'bellcranklever- 34, the hub of, which is rot-ated 'on 3 5-attbi:lower end of the stanchion 11, A center roperating link 36' fis;connected at one end to the bell levereand extends-'to the other side ofthe press, where it is connected to and 'operated `by the mechanismwhich operates `the unloading arm during that part of its movementfromidle position to the position shown in Fig. g3; The movement of the twostripping arms during the lower 90- orso of- `their arc of travel is thesame.

Ths`"cer'fer link is'pivoted between two. parllel arms 42 f of` p e...lever 44, the outline of which is f v lrom one side. of thezlever 44ex#- tend rthe two. lar; lel'trunnions '45 which are journaled on a`pinflfirtendiiiglacross Athe lower-side oi thel stanchion. i Y

Y Tioharre'st: thev downward movement of the links 55, in 1 11it;h. .lpos'ition-the unloading arms are in the horizontal position'vsholwn. inFigs.- 3 and 4, there is provided an adinstable abutment-in the path ofthe shaft 53. This is shown asa headed bolt 57 adjustably held in a lug58 mounted in the lower portion of the stanchion 40. When the shaft,`53is at the upper end of its movement, the unloading arms are in idleposition, as shown in Fig. 2, and when the shaft strikes the abutment 57the unloading arms have been elevated to the position where they are onthe level-of the upper end of the arm 15 at the upper endof itsmovement. This is through the action of: the piston rod which isactuated by the double acting cylinder 60 .which isheld in uprightposition by means whichwill bedescribed.

Theupper end of each link 55` is pivotally connected at 61to,a bearingsleeve 62. The two sleeves are connectedby an olset bridge piece 63 toform a U-shaped central membcr-.inwhich the two unloading arms are nlonrlwted.V Each unloading arm is given the numeral tvandiissenerally.L-shaned. Ybeing provided along its hpwrizpntal;portieri,- at theside ofthe diaphragm, with @infin-.which are mounted rollers 64b,

' Itfisdesirable t o,have the arms 64 mounted so that th e y,ca r xbemoved out ofthe way-to allow the lower moldgsections to be. changed.`For thisI purpose leach thefslecvei wher-ait` provided: with an enlargedhead 65. A spring 66 between the head 65 and the sleeve 62 urges the armupwardly. To each arm 64 below the sleeve 62 is welded a plate 67 whichunderlies the sleeve and carries a locking key in the form of awedgeshaped pin 68 which tits in a recess in the underside of thesleeve. This holds the arms in proper position but permits them to be`swung out of the way to allow for a mold change.

The sleeves 62 rock about a horizontalfsha'ft 70 nwhich is located inone corner of a lever which may betermed the cylinder bell crank,indicated asa f wholeby the numeral 72. This bell crank lever consistsof an clongated tubular shaft 73, intermediate of which a're welded twoheart-shaped plates 74r which. extend downwardly to either side of thecylinder 60, where they are provided with diagonally locatedV slots 75.'Located in the side of each plate 74 at the upper end of the slot 75 isa recess 74a (Fig. 8) in which is held a bearing 76. Thesebearings aredesigned to receive trunnions 77 proectingfrorn the sides of thecylinder 60. The parts are held together by snap rings 78. 'i

Also welded to the shaft '73, "but close to the ends thereof, are twoshorter curved plates 80, the upper edges of which follow the upperedges of the plate`sf74; At the points 70,`where the stripping lever islpivoted to the bell crank assembly,"r einforcing sleeves 8 2' arcsea tedin and welded to the vplates 7 4 and 80. I' At the other sid'epf `'thev`hell crank lever the platesv 74 and' 82am: aperturedtoreceive a' shaft 8'5 which is v located in the top of the' stanchion and'ab'out whichthe bell' crank lever rocked.'` Moverner'lt of the. hellc assemblyabout-the shaft is limited in clockwisefr'lreit-x tion by lugs 86: onthe plates 74 Aand' located' so' strike the top 'of a cross piece"87located `c rf'the` stanchion. Movement in the opposite direction 'is'limited by lugsv 88 striking a shaft 8 9 located' in the'top jof`thcstanchion.`

As shown in Fig. 5, lthe en'd ofthe clockwise rotation of the bell cranklever 72' is reached when the'unloa'dit'rg arm is at the top of itsstroke2 while the end. of' the anti# clockwise movement i's when thebell crank is 1`1 idle' position with the unloading arm horizontal asshownl in Fig. 3. i

Operation Just prior to the full opening of the press, a switch (notshown) is actuated which starts the diaphragm assemblyf in itsmovements. When the tire' is elevated' by the up'- ward movement of thediaphragm, pressure is admittcdt to the top of the cylinder 60, whichprojects the piston rod50 downwardly. This is because there is greaterresistance to upward movement of the cylinder'at this time; The downwardmovement of the piston rocks the crank lever 44 which, through the linkSS, will raise the left hand stripper arm. Through the center link 36this movement will also raise the right hand stripper arm. During theupward sweep of the stripper arms, the arms will pass under the tire, asin the a position in Fig. 1. During the continued upward movement thearms will go to the b position and strip the tire olf the diaphragm andat the same time the diaphragm s-being elongated so that it withdrawsfrom the tire. When the arms reach the horizontal or b position, alimitswitch -located in the lower part of the stanchion 11 (Fig. 7) isoperated by a cam- 96 on the hub of the bell crank lever 34. Theoperation of this switch shuts od the pressure to the cylinder 6i) whichcauses the arms to pause. This pause is suicient to permit the fullstripping of the diaphragm and the return of the diaphragm to itsv lowerposition. When the diaphragm reaches its seat inthe lower mold, anotherlimit switchlocated in the path of the diaphragm actuating means (not-shownl is actuated, which reopens the pressure line to the cylinder 60.

segnet When the uid pressure is now admitted to the cylinder 60, andbecause the abutment 57 prevents any further downward movement of thelink 55, the cylinder itself will rise, which, through the trunnions77,Will rock the bell crank assembly 72 in the clockwise direction. Themovement carries the unloading arm with it.

By comparing Figs. 3, 4 and 5, it will be seen that the raising of thecylinder shifts the position of the shaft 70, which causes the links 55to rock about their lower pivots and the. arms 64 to rock about thepivots 70. By following the several positions of the end of the arm 64from horizontal to the extreme raised position, it will be seen that thestripping arms move in a compound arc which moves the outer end of thearm upwardly of the diaphragm and over the top of the diaphragm. Themovement lifts that side ofthe tire well over the top of the diaphragmto the position where it will slide o the arm 64 and over the rollers onthe arms i5 to the point where it fallson the oli-carrying conveyor. Dueto the linkage which controls the movement of the unloading arm, thelast phase of its movement will be to the right as shown in Fig. 3,which gives the tire a slight nudge which starts it on itstravel. Themovement of the unloading arm above horizontal does not transmit anymovement to the other stripper arm 1S because the links 55 rotate onlyabout the centers 53, during the period that the bell crank assembly 72is operating. n v

At the end of the unloading movement, a third limit switch 99 located onone of the crossy pieces 87 is struckv by lug 86 on the bell crank 72,which reverses the fluid pressure in the cylinder 60 and causes the tirestripping arms 64 and l5 to return to the lowermost or idle positions.At that point another limit switch mit, located in the stanchion 11, isactuated by a cam 301 on the hub of the bell crank lever 34. This switchis located in the 4. In a press for shaping and curing tires on adiaphragm, a pair of swinging arms on opposite sides of the diaphragm tosupport and lift a tire along the diaphragm, means to cause said arms toraise simultaneously to a degree suflicient to shift the cured tire tothe top of the diaphragm, and means to cause one of said arms to`continue 4its upward movement while the first arm is held at its raisedposition.

5. In a `press for shaping and curing tires on a tire forming mechanism,a pair of swinging arms on opposite sides of the said mechanism, meansincluding across link to move said arms in unison from a lowered to araised horizontal position, and means acting on one of said arms tocause said arm to move upwardly thereafter while the other arm isstationary to a suflicient extent to cause the tire to pass out of thepress by gravity.

6. In a press for shaping and curing tires on a diaphragm, a pair oftire supporting and lifting arms on oppower line to the press closingmechanism and until this switch is closed the press will not close, thusinsuring that the arms will be fully lowered and out of the way of theupper mold section when the press closes. v

It will be seen that a very effective mechanism has bee provided bywhich the action of the stripping arms which are characteristic of thediaphragm presses of my design is carried forward, making it possible tounload a press automatically at the end of the curing operation.

It will be appreciated that in the broader aspects of the invention theparticular mechanism shown and described for raising both arms to thehorizontal position, and then continuing the upward movement of one .ofthe arms only, is not essential and may be modied or improved.
